They're hardy, so don't need protection, other than from really wet, windy weather while they're small. Having them outside stops them growing too quickly and softly, and is the best way to grow them. They germinate more slowly and make stronger plants.
However, if you've been growing them inside, keep pinching them out or they'll just get leggy and weak, and gradually get them hardened off a bit. You want strong, bushy plants when you get them out in their final positions. That way, they'll be less susceptible to slug attacks, and will grow on well.
